The copy of the text being edited resides in - a temporary file called the <i>buffer</i>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Commands to <i>ed</i> have a simple and regular structure: zero, one, - or two <i>addresses</i> followed by a single character <i>command</i>, possibly - followed by parameters to the command. These addresses specify - one or more lines in the buffer. Missing addresses are supplied - by default. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - In general, only one command may appear on a line. Certain commands - allow the addition of text to the buffer. While <i>ed</i> is accepting - text, it is said to be in <i>input mode.</i> In this mode, no commands - are recognized; all input is merely collected. Input mode is left - by typing a period <tt><font size=+1>.</font></tt> alone at the beginning of a line. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Ed</i> supports the <i>regular expression</i> notation described in <a href="../man7/regexp.html"><i>regexp</i>(7)</a>. - Regular expressions are used in addresses to specify lines and - in one command (see <i>s</i> below) to specify a portion of a line which - is to be replaced. If it is desired to use one of the regular - expression metacharacters as an ordinary character, that - character may be preceded by ‘<tt><font size=+1>\</font></tt>’. This also applies to the character - bounding the regular expression (often <tt><font size=+1>/</font></tt>) and to <tt><font size=+1>\</font></tt> itself. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - To understand addressing in <i>ed</i> it is necessary to know that at - any time there is a <i>current line.</i> Generally, the current line - is the last line affected by a command; however, the exact effect - on the current line is discussed under the description of each - command. Addresses are constructed as follows. - 1. The character <tt><font size=+1>.</font></tt>, customarily called ‘dot’, addresses the current - line.<br> - 2. The character <tt><font size=+1>$</font></tt> addresses the last line of the buffer.<br> - 3. A decimal number <i>n</i> addresses the <i>n</i>-th line of the buffer.<br> - 4.<tt><font size=+1> 'x</font></tt> addresses the line marked with the name <i>x</i>, which must be - a lower-case letter. Lines are marked with the <tt><font size=+1>k</font></tt> command.<br> - 5. A regular expression enclosed in slashes ( <tt><font size=+1>/</font></tt>) addresses the - line found by searching forward from the current line and stopping - at the first line containing a string that matches the regular - expression. If necessary the search wraps around to the beginning - of the buffer.<br> - 6. A regular expression enclosed in queries <tt><font size=+1>?</font></tt> addresses the line - found by searching backward from the current line and stopping - at the first line containing a string that matches the regular - expression. If necessary the search wraps around to the end of - the buffer.<br> - 7. An address followed by a plus sign <tt><font size=+1>+</font></tt> or a minus sign <tt><font size=+1>−</font></tt> followed - by a decimal number specifies that address plus (resp. minus) - the indicated number of lines. The plus sign may be omitted.<br> - 8. An address followed by <tt><font size=+1>+</font></tt> (or <tt><font size=+1>−</font></tt>) followed by a regular expression - enclosed in slashes specifies the first matching line following - (or preceding) that address. The search wraps around if necessary. - The <tt><font size=+1>+</font></tt> may be omitted, so <tt><font size=+1>0/x/</font></tt> addresses the <i>first</i> line in the - buffer with an <tt><font size=+1>x</font></tt>. Enclosing the regular expression in - - <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> - - <tt><font size=+1>?</font></tt> reverses the search direction.<br> - - </table> - 9. If an address begins with <tt><font size=+1>+</font></tt> or <tt><font size=+1>−</font></tt> the addition or subtraction - is taken with respect to the current line; e.g. <tt><font size=+1>−5</font></tt> is understood - to mean <tt><font size=+1>.−5</font></tt>.<br> - 10. If an address ends with <tt><font size=+1>+</font></tt> or <tt><font size=+1>−</font></tt>, then 1 is added (resp. subtracted). - As a consequence of this rule and rule 9, the address <tt><font size=+1>−</font></tt> refers - to the line before the current line. Moreover, trailing <tt><font size=+1>+</font></tt> and - <tt><font size=+1>−</font></tt> characters have cumulative effect, so <tt><font size=+1>−−</font></tt> refers to the current - line less 2.<br> - 11. To maintain compatibility with earlier versions of the editor, - the character <tt><font size=+1>^</font></tt> in addresses is equivalent to <tt><font size=+1>−</font></tt>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Commands may require zero, one, or two addresses. Commands which - require no addresses regard the presence of an address as an error. - Commands which accept one or two addresses assume default addresses - when insufficient are given. If more addresses are given than - a command requires, the last one or two - (depending on what is accepted) are used. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - Addresses are separated from each other typically by a comma <tt><font size=+1>,</font></tt>. - They may also be separated by a semicolon <tt><font size=+1>;</font></tt>. In this case the - current line is set to the previous address before the next address - is interpreted. If no address precedes a comma or semicolon, line - 1 is assumed; if no address follows, the last line of the - buffer is assumed.
